Increasing evidence from clinical studies in Intensive Care Unit (ICU) settings indicates that insulin infusion can improve outcome measures for patients with hyperglycemia (high blood sugar) independent of a previous diagnosis of diabetes mellitus. This improvement in health could also apply to patients that have high blood sugars in various other non-critical care areas of the hospital as well. However, the data that shows improvement in health outcomes has been collected from wards that have a lower patient to provider and patient to nurse ratio, resulting in the ability for a much tighter control of the insulin infusion. We hypothesize that tight blood glucose control will provide the same benefits for patients in non-intensive care units settings but that these protocols may lead to a higher incidence of hypoglycemia (low blood sugar) and potentially to adverse outcomes in patients.
